What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants That Were 2-level Composite (CR-PCSS and PR-PCSS) Responders During the Observation Phase

    Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS) and Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS) is a 5-level scale ranging from "0" (None) to "4" (Severe). A 2-level composite responder is a participant that received EN3835 with a reduction (decrease in score) in severity of at least 2-levels from baseline on both the CR-PCSS and the PR-PCSS at a particular visit.

    Observation Phase is defined as the time period from Screening to the first treatment date of the same treatment area in Study EN3835-202, or the end of Study EN3835-202 if there was no treatment received for the same treatment area in Study EN3835-202. Three participants were discontinued from the study after Day 180, percentages are based on the observed counts.

    Measured: Day 180 to Day 360

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Collagenase Clostridium Histolyticum in people with Edematous Fibrosclerotic Panniculopathy and Cellulite, run by Endo USA Inc., a Keenova Therapeutics Company at 15 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants That Were 2-level Composite (CR-PCSS and PR-PCSS) Responders During the Observation Phase (time frame: Day 180 to Day 360). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Nov 2020.
